Question

Complete the second row of the table.Express the volume in liters to three significant figures.

Answer 1

In this case you need to use the volume and temperature equation from Charles law.

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

We are given T1 = 139 k

T2= 317 k

V2= 176 L

We want to find V1. Now lets re-arrange the equation.

$V_1=\frac{V_2}{T_2}xT_1$

V1 = (176 x 139)/317

V1= 77.2 L
